JAMES NAYLOR, JR, OF ROCHESTER, ASSIGNOR TO BURRELL, IYES 85 00. AND DAVID H. BURRELL, OF LITTLE FALLS, NEW YORK:

MACHINE FOR POINIING AND LAPPING WOODEN BARREL-HOOPS.

SPECIFICATION forming part of Letters Patent No. 233,538, dated October 19, 1880,

Application filed October 28, 1878.

To all whom it may concern:

Be itknown that 1, James NAYLOR, Jr., of

the city of Rochester, in the county of Monroe and State of New York, have invented a new and useful Improvement in a Machine for the Pointing and Lapping of IVooden Barrel- Hoops; and I do hereby declare the following to be a full, clear, and exact description of the construction and operation of the same, reference being had to the accompanying drawin gs.

My invention relates to a simple machine, as will be hereinafter described, for the combined purpose of making a perfect point and a perfeet lap more readily than has been done heretofore.

The invention consists in the arrangement and construction of parts hereinafter described, similar letters indicating similar parts in all the figures.

Figure 1 is a plan view of the machine. Fig. 2 is a longitudinal section of the machine on line 00 .r, Fig. '1. Fig. 3 is a detailed view of the rest G, showing the shoulder or stop g.

A A represent the frame, which is so eonstructed that the two bearings E E are on the same solid casting, which insures their always being in line.

B B are wheels carrying knives which do 0 the work. These wheels are turned off true ontheirinsideface. Theknives,setattheproper angle and projecting somewhat to give the required cut, are securely attached to both wheels. Oneofthesewheels,B,hasastraight 5 face, while the other, B, has its face of sufficient angle to form or create the opening 0 between the wheels, which coincides with the required point of hoop. These wheels are secured together on the arbor D, which runs 40 freely in the bearings E E, being driven by a belt over the pulley F.

G G are rests for placing the hoops while being operated upon. G, the one used for pointing, has an elongation outside the pc- 5 riphery of the wheels, with the guides H H,

for the purpose of keeping the hoop while being operated upon in a correct position. In

other machines the wheels alone are depended upon. In the present case this would not do, as the wheel B has much more work to do than the other. Therefore the knives get dull sooner and would crowd off the hoop to the other wheel having the sharpest knives, and so make the point all one-sided, were it not for the guides H H holding it securely in the proper line. G, the other rest, is on the opposite side of frame A. Here the knives cut upward, while at the rest G they cut down.

In presenting a hoop to be pointed, to obtain the required point it necessitates placing the rest G with the guides H H oblique to the square of the frame. This enables the operator to stand immediately in front of the machine, and in good position to pass the already-pointed hoop to the other operator without its being turned, which is a very important point when the rapidity of the work is considered. This passing of hoops during the operation is not new; but it is the more favorable positions which the operators can take in the prescut instance which enables them to do the same amount of work much easier than in all other machines. The other operator laps the hoop by aid of the rest G on the straight-faced wheel B, the hoop being guided to its position by aid of the guides I I. The required taper of lap is obtained by its adjustment to the straight-faced wheel B, the rest G serving this purpose.

The operation of my machine is as follows: The operator places himself immediately in front of the machine. The knives here are cutting downward. He takes a hoop and places it between the guides H Hand pushes, or rather the knives draw, it in between the wheels 13 B. As soon as the formed point comes in contact with the extremity of the opening 0 it is withdrawn and conveniently handed to the other operator without its being turned, who presents it, by aid of the guides I I and the rest G, to the straight-faced wheel B. The hoop is pushed and drawn in as in the pointing. The knives here cut upward, and to hold the hoop from rising there is square shoulder g, forming part of the rest Gr. 5 Thus is made a perfect lap on the same machine and on the same wheels that made also a perfect point.

When the lapping is done on a wheel having an oblique face, it cuts according to its face, which is to make thelap thin in center, and consequently, when it is nailed and clinched,it invariably cracks; and it no nails are driven Where it laps, the hoop must have so much more stock or material in it for the point to well overreach the lap. In and by the use of the improvements herein described both these objections are very easily overcome.

There is nothing new in the fact of pointing hoops on :WI'IGGIS, the hoop being presented betweenthem. Neither is there anything new in lapping hoops on astraight-faced wheel. Such are in constant use, as hereinbefore alluded to; but, 1 V

Having thus described my invention and shown clearly the difference between the new and the old, that anyperson ofreason unskilled in the art to which it applies may readily understand and appreciate the improvements thus described, I claim as new and desire to secure by Letters Patent the following:

1. In a machine for the combined purpose of pointing and lapping hoops, the combination of the straight-faced wheel B for lapping with the oblique-faced wheel B for pointing said hoops, both wheels mounted on one arbor so as to face each other, substantially as shown and described.

2. In a machine for pointing and lapping hoops, the combination of the wheels B B on same arboronc fiat, the other inclined-and the rest G, set obliquely to the arbor D, for the purpose of holding the hoop in position to receive the action of the knives in said wheels, substantially as specified.

3. In a machine for pointing and lapping hoops, the combination of the elongated rest G and guides H H, extending beyond the pe ripheries of the wheels B B, one having a flat and the other an inclined face, and arranged to present the hoop in proper position to receive an even point, substantially as set forth.

4. In a machine for pointing and lapping hoops, the combination, with the wheels B B, one having a flat and the other an inclined face, of the rest G, set at right angles to the arbor D, for the purpose of lapping the hoop on the straight-faced wheel B, substantially as specified.

5. The combination of the wheels B B, with their different faces, the oblique pointingrest G, and the lapping-rest G, all arranged substantially as shown and described, and for the purposes herein set forth and specified.
